'(' or '[' Expected

Question

I am getting the following error when trying to compile my program.

'(' or '[' Expected.

 public AccountArrayList()
{
    // line one below is the hi-lighted code
    ArrayList accounts = new ArrayList;
    accounts.add("1");
    accounts.add("1");
    accounts.add("1");
    accounts.add("1");
    accounts.add("1");
    accounts.add("1");
    accounts.add("1");
    accounts.add("1");
    accounts.add(5,"900");
}

Thank you.

Answer 1

You're missing parenthesis on the constructor:

ArrayList accounts = new ArrayList();

Answer 2

Your constructor is wrong. It has to be;

ArrayList accounts = new ArrayList();

Answer 3

If you are using Java 5 and higher, you will see that ArrayList uses generics.

You can essentially to this:

ArrayList<String> accounts = new ArrayList<String>();
